Radiation sensor BT70i is sensitive to alpha, beta and gamma radiation. Alpha, beta and gamma radiation ionise the material the radiation falls on or passes through. The amount of radiation is generally determined by measuring the degree of ionisation it causes. The radiation sensor uses a Geiger-Müller counting tube to detect this radiation.
When the GM tube detects a decay event, there is a short time in which no other decay event can be detected. This is called the dead time. The maximum dead time of the GM tube is 90 microseconds (90 µs).
Suggestions for experiments
- Measurement of background radiation
- Measurement of radiation from known radioactive materials
- Radioactive decay and half-life determination
- Radiation level against shielding thickness or material
- Measurement of radiation from a beta or gamma source as a function of distance between source and sensor.
The Radiation Sensor can be directly connected to the analog BT inputs of the CMA interfaces.
